air shocks

All right, I have air shocks on my Dart. Never had them on any car before, the car came with them. The *** end is way up in the air, definitely not the correct ride height. If I'm not mistaken, the rake is actually making the nose dive down a bit. Eventually I will change the whole rear suspension set up but for now, they're staying.

Just as a quick check, I put a tire gauge to the little schraeder fill valve and it was way over 50psi. Obviously I need a better gauge to see what it actually is but in lieu of that - is there a recommended setting or is it just personal choice? Feels like the thing is hopping around back there. I'd like to lower it down a bit and soften them up if possible.

Thanks,

Greg
